The C++ Language Support for Xcode 15

Xcode 15 beta is out and Apple now has a page which I I'm not sure if it was there before. They have a page called C++ language support where the list basically what Xcode and Apple Clang supports with links to all the relevant papers. This one is on the Apple website so it seems like more official so that could be useful. On the other hand the CPP reference table also has all the stuff that Apple Clang doesn't yet support which the Apple website obviously doesn't list.
